Application led Noveinber 21, 1921. Serial No. 516,634.

This invention relates generally to an in# 10 dex card for vertical tiling vcabinets and more particularly t0 an indexing strip holder for the upper margin thereof, or for other types of filing systems.

ln devices oi' this character which are 15 shuffled over hastily and frequently by iinger manipulation, the indexing strips, from continual handling, become iiexed or broken, the indexingvcharacter becomes soiled or mutilated, and it is an object of the invention to overcome these two detects by providing an index strip holder which will reenforce the index card margin and which will transparently display the index character printed upon the strip while preventing said strip from becoming soiled or displaced.

` Another object of the invention is to pro vide a structure ready for use of any desired indexing character interchangeably with any particular index card.

' Another object of the invention is to provide on the front face of the card margin to be indexed, a permanent transparent index strip holder, presenting the strip at the proper angle of vision, enabling the index strip to be readily inserted or removed, and

formed in such manner that while the holder Y reenforces the card margin at this handling point, the index strip when inserted in place, also reeniorces, strut-like, the structure ot the transparency.

These and other objects "of the invention will' be fully set forth in the description or the accompanying drawing, in which:

Figure 2 is a large detailed view oi the tab-holder. y Figure 3 is a cross section on line 3, 3, Fig. 2. Y

Figure 4 is a plan view of the index tab. For convenience, an ordinary index card or sheet is shown, Fnumbered l, having the odset marginal bottom portion 2, of conventional form, provided with the orifice 3, slidably engaging the cabinet element in Figure l is a face view of an index card.'

conventional manner. The upper marginai edge of this card is formed with a projecting tongue 4, for positioning and securing the index strip. lt will be understood that 1n usage, the series of card tongues are oi- @o set in relation to one another to throw4 them into a single vision ield. To the upper margin of the card'and upon this projection i is securedan index stripholder 5, formed of transparent material, such as Celluloide G5 The flexible or relatively stiii strip of" celluloid is folded over the marginal portion 4; of the card, so that its opposite ends overlap' upon opposite sides of the card and are secured to one another and to the intermediate 7G card by eyelet rivets 6, the intermediate portion of the strip being so folded over the tab of the' card as to provide a definite shaped receptacle, approximately a triangular crosssection, and, the base of which, 7, 'Z5 is the reading transparency properly displayed in the angle of vision. This receptacle is so formed that the angles adjacent this reading` plane or panel 7 practically form a seating guideway for the endwise insertion-and retention of an index strip 8, ordinarily of cardboard, having an appropriate index character 9.

ri"he utilityof this device is enhanced by its extreme simplicity, enabling a substantial reenforcement of the index margin of the card, making a permanent transparency for rigidly supporting and displaying the index character oi an interchangeable strip, being sanitary, always legible and protected, and @e supported upon the data face of the card.

The index holder so constituted forms a light, compact instrumentality for the card manipulation, as the tab e enters and ex tends to the top oi the container, it is in on effect, integral with the card.

The margin 'of the card is reenforced from a point below the projecting tab 4f, while the index insert strip, and the tab portion of the card, form two angle Vbraces interior of the to@ container,holding it denitely on the data face oia the card, so that it constitutes a sort of handle index for manipulating the card.'

Another advantage oit this structure is the avoidance of adhesively secured tabs or into@ dex characters or the use ot index tabs which expose a printed index character to the air or the moisture ont the hand, and, in addi@ tion, it is oadvanta to have this index what e metadati@ nature mi@ Having described the invention, I claim:

l. An index card having a flexible strip of transparency folded over one margin and secured upon opposite surfaces of the card reinforcing the same, the medial or fold portion of the transparency forming a, receptacle open at opposite ends and approximately triangular in cross section to constitute a display panel at a proper anglev of vision, an index strip placed within the said receptacle between the panel and the margin of the index card and held in place by them.

2. An index card having a tab portion at one'end, a flexible strip of transparency folded over the margin of the tab and secured upon opposite surfaces of the card for reinforcing the same, the medial or fold portion of the transparency forming a receptacle open at opposite ends and approximately triangular in cross section to constitute a display panel at the proper angle of vision. an index strip placed Within said receptacle against the panel and contacted atan angle by the margin of the tab, thereby holding said index strip against said panel.

lin witness whereof, I hereunto subscribe my name, as attested by the subscribing Witness.
